\VIIRE-TWISTER FOR 'BLING-MACHNES.

Application med .rapaaryen 1914. serian no. 815,818.

To all fiche-m itmy concern? Be it known that we, LnnoYfD. and Q LrvnieGr. SHAW, citizensofmthe United States,"1'esiding at Monroe, in the county of Y*Jasper* and-.State o f'ow a,have invented a certain-- newand vuseful VireTivister for aehinges, of whichthefollowling is lon? y '5 sting device of `sim le, durable ti'vefi'n ac't'i n ,'=and` especially designed to Vbe automatic hay tyinafpre.

QA urther object is to provide an imp-oved Wire'engaging Vand holding device to used fin connection'with .a rotary twisting memberandso constructed that the wire member-is rotated;

Oui( invention consists 'in certain detaiis, 'in the construct'lom''arrangement and combiyvi'll be 'positively held end tiv'i'sted as the nation'of the various parts of the device,

whereby the {object s V.contemplated are attained, as hereinafter more fully set forth,

pointed out-'inour claims` and illustrated in the accompanying drawings, in which:

Figurel shows a-'cross .sectional view of a'baling box in 'which our, tying device is mounted.I Fig. l2-shows a top view of the same. Fig; 3shows .a detail, side elevation of the tying member, and Fig. 4 is a detail view showing the manner in which the wires are supported and also 'showing the position they take before the twistingoperation commences.

Referring tothe accompanying drawings, the reference numeral 10 indicates the top, 11 the bottom, and 12 thessides of an ordinary billing-box.' ',Thetop 10is provided with a transverse member 13 and-the bottom is provided with a similar transverse member 14. The ends of these members extend lconsiderably beyond the side of the baiing the frame 17 are two gear members 18 each eryto its'center.V The center et 'of our invention is to .provide pensive construction W ich is posi"- ha-ving a siot f1.9 extend'ing. .-f 1onifits periphof said-gear 'in provided withe hub 2 0, said hub being dei u .signedixto rotate in the sides ofthe frame 17. fihe frame i? 1s provided with slots extend? Y mg fronrone edge toward the' center and isdesigned to in line with the slotI 119 when the slot 19 i`s in a horizontal-position. A, lever 21 is pivoted in the bottom of the Siot 19, said lever being provided 4with' laterally" extending arms 22- near its'pivoted'end, the lever 2i being tapered toward itsfree end and designed to he on the bottomv of the slot.

when'in its normal position. W'hen a' Wire liters the slot 19 it "will engage 'the upper .me of the arms 22`and cause the free end of the lever 2 to be elevatedso that when e second Wire enters the groove 19 it will pass beneaththe: iever 2-1. VThis Wij-1l separate the two wires and at the same time prevent them from rotating relative tothe' gear member.' 18, as saidv gear-is rotated.

Thus it will be seenthetes the' "'ear'l' is i,

rotated by means of the mechanism' t0 be hereinafter described, the wires within said gear will also be rotated.

. For'meving t' i ne wires into the slot`19,' We

'23 is slidingly mounted in the grooves 15 and is designed to rest'outside of the baling box when in its normal position. This bar 23 is provided with two notched arms A vertical sha ft 25 is rotatably mounted .in the bars 13 and 14 and is provided Awith an arm 26 near its central portion, said arm beingv have provided thelfolion'ing device: A. bar,A

sri

operatively connected With the bar 23A byA means of a link 27. A. shaft 28 isrotata-blyv mounted in the iopposite ends of the bars v13 and 14, from which the shaft 25 is mounted, and is provided withv two arms 29', vsaid arms being operatively connected with the Vframe 17 by means of the links 30. The upper end of the shaft 28 is provided with a'bell crank iever 31, one end of which forms 'a hand lever' 32. An arm 33 is'secured to the upper end ofthe sha ft 25 and is connected to the bell crank lever 31 by means of a link 3 Those shafts are so arranged that as th lever 32 is rotated in the direction indicate by the arrow, the frame 17 and the bar 231:

will be moved toward cach other until the notches in the arms 24 are directly oppositev the central portions of the gears 18. The

roo'

bers 17 and has 'abeveled gear 37 on its outer end. The beveled gearA 37 is in mesh with a beveled gear 38 mounted upon the horizontal shaft 39. This horizontal shaft 39 is secured to the frame 17v by meansof the brackets 40 and has a crank 41 on its free end by which said shaft may be rotated.

To prevent the' lgears 18 from rotating when the crank 41 is notbeing operated, and to keep the slots 19 in a horizontal position, we have provided a pawl 41.*.pivoted tothe Side of the frame'17 air'dhavi'ng its hooked portion heldin engagement with the teeth of the gear' 35 by means of a'spring'42a. When it is desired to rotate the gears 18, the pawl 41i is rst moved/out of engagement with the gear 35. j

For severing the wires after they have been twisted, we have provided va pair of shears 42 secured to one side of the frame 17 and adjacent to each of the-slots 20. These shears are operated by means of a lever 43 and the links 44, the lever 43 being pivoted;

' matically by some mechanism from the baling press. y l

Onv each siderof the baling box, two sets of wires 46 are provided and those on the left side are in line with the notches in the arms EA. Those on' the right hand side of the box are in line with the grooves 19. It Willhe seen that as the lever 32 is operated,- the 7u' 23 and the frame 17 will be moved to-' yard each other in the slots 15 which will cause the wires on the right hand side of the machine to enter the groove 19 and pags over the 4top of the lever 21, thereby ca; ing said lever to move to the top of the groove 19. As the frames are advanced, the wire on the left hand sideof the machine will be moved toward the frame 17 and will also enter the groove'19and pass beneath `the lever 21, at which time the wires 46 will beat the central portion of the baling box, as Aillustrated in Fig. 4. 'As the crank 41 is operated, the gear 35 will be rotated and with it the gears 18 which will cause the two wires to be twiste around each other, after which the lever 3 may be loperated and the twisted portion of the Wire severgd.

, Thus it will be seen that as the gears 18 are impossible for the wires to rotate relative to the said gears.

It is to be understood that this device may be used in connection withany wire twisting device which has a rotary twisting member and slot s imilar'to the one in the Y gear anda radial slot, the width of-the slot in these cases being practically the same as the diameter of the wire Vvused. vAfter the wire twister has been used for some time,- the slots willfbecome worn .and permit the wires to rotate within them. It is also difficult to twist more than one sized wire. These objections we have overcome by employing the lever 2l.

IVe claim as our invention:

1. In a wire twister, the Combination of a rotatable member having n .slot therein to receive wires, and a pivoted lever within the slot, said lever being formed with wire en' gaging arms at its sideedges, for'the purposes stated. l i

2. In a wireptwister, the combination of a rotatable wheel having-a slot therein to receive'wires, a lever pivoted within the Ywheel with its free end in said slot, said lever being provided with, arms at each edge,` and means for rotating the wheel.v

3." In a A)vire twister, the combination of a rotatable member having a slot extending to its central portion, a pivoted lever in said slot, said leger having opposite arms where by the lever is automatically moved by wires toward-the side of the slot on which thewire engages the lever so that when two wires are successively placed inthe slot they will always stand on opposite sides of the lever.

4. In a wire twister, thecombination ofia rotatable wheelhavingaslot therein to receive wires, a lever pivoted within the wheel with its'free end in saidslot, said lever be: ing provided vwith arms at eachedge, means for rotating the wheel, and vmeans for locking the wheel against rotation.
